No workout to do today...and come to think of it....NOTHING AT ALL to do today really. I think I'm gonna stay in the house and be a slob all afternoon....it's good to do that once in awhile.

samoth said:So relativity states that if you have an imaginary invariant mass less than zero, you must travel at velocities greater than the speed of light. But what if you have real mass, and it's less than zero?
A cat is placed in a sealed box. Attached to the box is an apparatus containing a radioactive nucleus and a canister of poison gas. The experiment is set up so that there is a 50% chance of the nucleus decaying in one hour. If the nucleus decays, it will emit a particle that triggers the apparatus, which opens the canister and kills the cat. (According to quantum mechanics, the unobserved nucleus is described as a superposition (mixture) of "decayed nucleus" and "undecayed nucleus".) However, when the box is opened the experimenter sees only a "decayed nucleus/dead cat" or a "undecayed nucleus/living cat."
The question is: when does the system stop existing as a mixture of states and become one or the other?

Anthrax said:
The wavefunction collapses the moment the box is opened. At that moment, the cat has been dead or alive the entire time.
Long thought of as a paradox, Schrodinger's Cat-in-the-box is easily explained by quantum mechanics. The problem is that QM and the "real world" governed by Newtonian mechanics obey far different laws. That is why so many people and students are all like WTF when exposed to QM or SR.

samoth whats your take on multiple universes, i read a little on it, string theory i think it was called
Anthrax said:
I honestly have no idea. I never hear much about it... but I hear lots from CERN, Fermi-Lab, and SLAC all the time. I think it's something the nuclear engineer majors discuss/hear about more.
I've read a few quips about ITER on physics forums I think, but for what is supposed to be such a big, expensive, multi-nation project, news is sparse, at least where I live.

It's huge and if it will be the next nuclear plant generation, which will procvide most of energy when oil will become too expensive to extract

what does that have to do with multiple universes?Anthrax said:
hamstershaver said:
Eeeeeehhh... Umm, technically, M-theory (general names covering all the individual string theories) is actually a quantum gravity theory.
There's four fundamental forces in the universe. We know how to unite two of them, bringing us down to three outside of theoretical theories. Grand Unification Theories (GUT's) bring us down to two fundamental forces. Theories of everything (TOE's) bring us down to one.
String theory's main opponent is loop quantum gravity (LQG), however this one is much less popularized by media. Twistor theory was another one, but it was kinda eaten up by LQG, I think.
If you want an interesting video series about string theory go to
http://www.pbs.org/wgbh/nova/elegant/program.html
That Nova series explains things pretty well, but doesn not even tough the controversy surrounding string theories, LQG and QGT's amoung theoretical scientists today. The math is very complicated, since it involves the geometry of our existance, things get horribly complex, tensors are usurped by spinors, which are replaced by twistors and lie algebras, non-commutative differential geometry, topological group theory, and enough abstraction to drive anyone mad.
Remember, however, that descriptions such as "strings", "knots", and etc mean nothing. They are merely abstract words chosed to describe mathematics so that things are able to be explained to the public in a short, concise manner. The downside is that physically interpreting things at this level is simply wrong.
I think string theory spits out gravitons, too. That alone will have theoretical physicists and astrophysicists drooling, and relativists foaming at the mouth.
There were some really cool overheads from Twistor theory that Penrose wrote up for his graduate lectures some time ago. If I find a link to them, I'll post them... or I'll try to upload them somewhere since I got 'em saved.

damn the article i read must of been multiple universes for dummies, i dont understand one thing samoth is saying 
LOL I didn't even answer your miltiverse question.
Different string theories have different numbers of dimensions. Some have 7, or 9, or 11, of 21. There's three really big ones, but I don't recall which three.
The reason for this is that the have all these equations, and try to manipulate them. Depending on who's doing what, they'll spit out different numbers.
All dimensions beyond our familiar four are theorized to be "curled up" into our reality. That is, the other dimensions predicted by string theory are actually tiny dimensions smaller than an atom "curled up" into our four macroscopic dimensions. We don't actually exist in these dimensions because they are so small.
The videos explain this concept well, and actually have a little video thing that lets you visualize how the other dimensions are wrapped up on themselves and curled up into our reality.

nuclear plant = electricity = what enables you to get K here through your PC (along with seeing boobs pics)
multiple universes = a bunch of theories that will still remain theories in the next 10 years and which have absolutely no practical effect on your everyday's life
So my answer to your question is "who gives a shit ?"
Anthrax said:
I'm hearing more and more that engineering/physics/chemistry or any formal education related to hydrogen manipulation will be the most desired on earth come lower oil supplies.
The ITER thing is something I really need to do more reading on, 'cause I know very little about the entire thing. I'm more into astrophysics and the std model, so if this plant isn't involved in research or accelerators, that's probably why I don't hear much.
Man, I'd love to intern at a place like that for a summer.
Anthrax said:
LMAO!!
Anthrax said:
10?? That'd be a theorist's dream. I'm hoping they have something in the next fifty years. The problem with this stuff is that we've exceeded experimental limitations, so we can't test for much. If we're looking for particles at, say, 750 TeV, we really can't create those conditions on Earth. And when we're talking experimental verification of some of these far-out TOE's, we pretty much need the energy equivalant of what a Dyson sphere encompassing a type-O or B star would harness.
Anthrax said:
I just wish they'd devote more funds to space research, period.
The whole shuttle thing really bugs me. Granted, these men and women died, but c'mon. They knew the risk. They died for one of the most honorable causes in the history of our planet. And what, say 10 people died. Ummmm... hello? 10? Ten? I don't see them banning automotive travel when people die. Nor do I see them banning biolobical or anthropological field studies when people die? And don't even get me started with the damned chemists.
Yet they want to shut down/delay the whole space thing for all these years because of literally a couple deaths? Hell, I'd be honored to die in the manner they did. I'd sign up in a heartbeat, even with odds in the favor of my not coming back.
hamstershaver said:damn the article i read must of been multiple universes for dummies, i dont understand one thing samoth is saying
Seriously, watch the videos I posted. They're PBS Nova series. They explain things really well and with visualizations and little movies and everything way way better than anyone could ever explain to you simply writing words.
It's free and stuff, and divided into a bunch of parts, so you can, like, watch it over a period of time or between commercials or something.

apart from the huge impact of human dying in front of millions of TV viewers there is also the cost of those programs !
The US can't afford to launch new space projects alone
It must be an international collaboration
Let's hope Bush is better for that than to convince his "allies" to send troops in Iraq

Well, if they'd stop wasting money and people in other county's trying to dictate all these politics and stuff, the financial allotment of the space program would triple! lol
I don't follow politics at all, so I know I'm ignorant on the general issue, but...
The US government has a lot of money. They do a lot of things with it, and that money goes to many different areas. Some more, some less. I just have trouble comprehending why so little goes to space research. For all the money NASA has, they're dirt poor. So much stuff there is ghetto beyond belief. The final projects we see on TV are only a very, very small fraction of the money needed for that whole project.
The whole shuttle-oring-insulation thing. If NASA wasn't so damned strapped for cash that they cut corners 5 out of every 4 times, that never would've happened.
And the "impact of human dying in front of millions of TV viewers"... well, I don't see CBS or NBC or FOX news stations getting their budgets cut whenever they show people dying. People like watching tradegies, and it actually makes stations money. Besides, the clip of the little blip lighting up and disappearing isn't very scarring to the American public, or even children for that matter. It wasn't exactly graphic.
Anthrax said:
I'll never understand why people are so engulfed by their petty differences and continue to obfuscate future generations to come.
"Their country isn't as good as my country", which expands out to
"Their culture/religion/laws/way of living isn't as good as my culture/religion/laws/way of living", eventually culminating with
"They aren't as good as me."
So we all stop talking to each other and do our own little thing.
Anthrax said:
Very true. But, I don't know. That's so short term. If we're launching space torpedoes from our starship in orbit at Iraq, we'd get that expected oil $ a lot quicker!
I don't even know the entirety of the reason why we're in Iraq. Oil, restructuring their government, etc. I really despise politics, but can't really argue them either way, since I'm totally ignorant on the subject.
Mr. dB said:
That's right, wasn't he a graduate student in Spain with a BS in nuclear physics?
I read some of his science stuff before, and wasn't too impressed with the way he came across. I couldn't tell if he knew what he was talking about or not. The only way to "call out" a person on this subject is to go over to a forum that supports LaTeX, and start throwing the math around. Anyone can Goggle "nuclear physics", but when you start discussing probability density of virtual exchange mesons between nuclei and someone doesn't even know the magnitude of the energy/momentum four-vector, they get laughed off the board pretty quick.
